FRONT-EDGE SHEET-REGISTERINGMECHANISM FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 567,730, datedSeptember 15, 1896.

Application filed May 31, 1895.

To all whom it may concern:

Be it known that I, HENRY A. WISE Wool), a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Improvement in Front-Edge Sheet-Begistering Mechanism for Printing-Presses, of which the following is aspecification.

The aim of this invention is to provide a new and improved automaticregistering mechanism for bringing into register the sheet placed inapproximately the desired position on the feed-boardof aprinting-machine.

To this end the invention consists of the device described and claimedin this specification, and illustrated in the accompanying two sheets ofdrawings, in which- Figure 1 is a sectional elevation of the mechanism,showing the sheet placed in approximately the desired position. Fig. 2is a similar View showing the sheet as grasped by the grippingmechanism. Fig. 8 is a similar view showing the sheet brought to theexact position. Fig. 4; is a similar view showing the gripping device asopen after the sheet has been brought to the desired position. Fig. 5 isa similar view showing the gripping device clear of the sheet. Fig. 6 isa detail view, on an enlarged scale, of one of the sliding frames. Fig.7 is a diagrammatic view showing the positions assumed by the sheet, andFig. 8 is a sectional elevation of one of the clamping devices that Ipreferably employ.

Referring to the drawings, it will be seen that I have shown in diagramenough of the mechanism of a printing-machine to enable my device to beunderstood.

B designates the usual impression-cylinder of any printing-press, and Fthe feed-board thereof.

Extending up from the framing of the printing-machine are brackets, asA, and in these brackets is mounted a shaft 10. Rigidly mounted on thisshaft 10 are a number of brackets 11, the number of brackets used depending on the number of gripping devices that is desired, two or morebeing used, depending on the width of the machine to which my inventionis applied. Arranged Serial No. 551,289. (No model.)

in each bracket 11 are suitable boxesor bearings, as 12 and 13, in whichthe journals 14': and 15 of the slidingframeD fit. The frame D has adownward. extension 16, the edge of which next the feed-board forms whatI hereinafter term the registering edge. On the bottom of each extension16 is secured a projecting lip 17.

18 represents a screw on which is pivoted asuitable gripper or jaw 19,which is arranged to coact with the extending lip 17 to form a grippingdevice. This gripper 19 is normally kept against the lip 17 by means ofa spring 20, as shown. This gripper has an extending arm 21, whichcarries a roller 22 arranged at an angle to the jaw 19, and an extension23 carrying a roll 2 1 arranged substantially in line with the jaw 19.

The sliding frame D has a projecting hub 25, and between this hub 25 anda hub or part 26, mounted on the bracket 11, is arranged a spring 27,which tends to normally pull the sliding frame D to the right to theposition shown in the drawings.

A trigger 28 is mounted on a'screw 29 secured in each bracket 11, and aspring 30 is arranged,as shown, between the part 26 and the trigger 28to keep the upper end of the trigger normally pressed against the hub orprojection 26.

The sliding frame D is connected to a hub or yoke 31'by a right and lefthand screw 82, as shown, so that an adjustment may be made between thehub or yoke 31 and the sliding frame D. The hub or yoke 31 carries aroller A shaft 31 is journaled in arms extending down from the brackets11, as shown. Mounted on one end of this shaft is a lever 35, which isconnected by a suitable link 36 to any suitable actuating mechanism, asthe cam mechanism ordinarily employed for this purpose. Also mounted 011this shaft 34: are a number of fingers 37, a finger being pro vided foreach frame D, and these fingers are arranged so as to catch and bear onthe rollers 33 of the yokes 31, as shown. A shaft 39 is also journaledin projections extending from the brackets 11, and on the end of thisgrasp and seize the edge of the sheet.

shaft is mounted a lever 40, which connects by a link 41 to any suitablecam mechanism ordinarily used for this purpose. A number of fingers 42aremounted on this shaft 39 in position to engage each of the rollers 24of the gripping-jaws.

Mounted on the rear end of the shaft 10 is an arm or lever 43, which hasa bolt 44 connected thereto, and which bolt passes through an extensionon the rear frame A, and is held in place therein by means of nuts 45and 46, by adjusting which nuts the position of the gripping-jawsrelatively to the feed-board can be accurately and nicely determined.

A shaft 100 is mounted transversely in the machine over the feed-board,as shown, and the same carries a number of registering-fingers 101,which have the downwardly-extending registering-pins 102 and springs103.

The operation of this mechanism is as follows: A sheet is placed inapproximately the desired position on the feed-board F and so that theedge of the same extends within the gripping-jaws, as shown in Fig. 1.The sliding frames D will then move toward the feedboard and will bringthe registering-edges thereof against the edge of the sheet, which willbe slightly buckled or crowded upon the feed-board, as indicated at S inFig. 7. As the gripping-jaws move past the triggers 28 the jaws will beopened, but when the sliding frames move a sufficient distance to theright the rollers 22 will clear the triggers 28, and then the springs 20will force the jaws 19 to This will bring the parts to the positionshown in Fig. 2. Then the sliding frames will move to the left adistance greater than that which they previously moved to the right. Asthe rollers 22 in this movement pass by the triggers 28 they will movethe upper edge of the triggers away from the hubs or projections 26, andthe jaws will not be opened thereby. This movement to the left of theframes D will bring the sheet to the exact position S- which is desired,or to the position shown in Fig. 3. I generally use the registering-pinsshown in Fig. 8, and the same are arranged on the shaft 100 so as tointermesh with the gripping devices. These fingers are so arranged thatwhen the sheet is pulled into proper position the front edge of the samewill rest against the fingers 102, and so that the springs 103 will holdthe sheet in exact position until the same is taken by the grippers ofthe impressioncylinder, when the fingers will be raised to release thesheet. Of course the springs 103 will be held away from the feed-boardwhile the gripping devices are bringing the sheet into proper registeror against the registeringpins 102. I have not shown theseregisteringfingers in the sectional elevations, Figs. 1 to 5 inclusive,as the same would tend to interfere with the proper showing of thegripping devices. I intend in some cases to omit these fingers anddepend merely on the sheet being brought to position by the grippingdevices,

but for most cases I use these fingers. After the sheet is brought tothe position shown in Fig. 3 the rod 41 is actuated so that the fingers42, bearing on the rollers 24, will open the jaws, so that the grippingdevices will be clear of the sheet. This position of the parts is shownin Fig. 4. After the sheet is brought to the position shown in Fig. 4,the sliding frames D will be moved still farther to the left, so thatthe'gripping devices will clear the sheet, as shown in Fig. 5, so thatthe sheet can be taken by the grippers of the impression-cylinder. Thusa sheet placed in approximately the desired position on the feedboardwill be brought automatically into exact front register or exactposition, so that when the same is taken by the grippers of theimpression-cylinder it will be in exact position so far as its frontedge is concerned.

The details and arrangements herein de scribed may be varied by askilled mechanic without departing from the scope of my invention asexpressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination in a sheet-registering mechanism, of a sliding framehavinga gripping device, a registering edge in said gripping device,means for moving said gripping device so that the registering edge willcontact with the sheet and slightly buckle the same, means for thenmoving the-gripping device in the opposite direction, and a triggermechanism arranged so that the movement of the frame toward the sheetwill open the gripping device and so that when the sheet has beenbuckled, the gripping device clears the trigger mechanism releasing thegripping mechanism to seize the sheet, substantially as described.

2.
